我们已经开发出一种新的架构，以非常高的速度处理二维数字图像数据。该架构是用FPGA实现的，只提取X射线CCD的原始帧数据的天文用途的X射线信号。电路规模小到足以在目前可用于空间使用的FPGA中实现，同时实现107像素/秒的数据处理速度。该架构原则上可适用于广泛的应用。
We have developed a novel architecture to process 2-dimensional digital image data with very high speed. The architecture is realized with an FPGA to extract only the X-ray signals from the raw frame data of an X-ray CCD for an astronomical use. The circuit scale is small enough to be implemented in an FPGA currently available for a space use, while the data processing speed of 107 pixels/sec is achieved. The architecture can be adapted in principle to a wide range of applications.
